Gladiator Challenge and Palace Fighting Championship veteran, Danny Castillo (5-0), will step in for an injured Rich Crunkilton to face Donald Cerrone (7-0) at WEC 34: "Faber vs Pulver" at the Arco Arena in Sacramento, Calif., on June 1.
The Zuffa-owned promotion recently confirmed the lightweight match up on its Web site.
Castillo has only been fighting nearly a year and a half; however, his five victories have all ended in the first round -- four via submission and one technical knockout. "Last Call" -- who will make his WEC debut -- is a two-time National Association of Intercollegiate Athletics (NAIA) All-American wrestler out of Menlo, Calif.
Meanwhile, his opponent, Cerrone, is currently riding a seven-fight winning streak of his own, defeating Kenneth Alexander via submission (triangle choke) at WEC 30 in November 2007. However, it was later ruled a "no contest" because Cerrone was found to have a banned diuretic in his system after the bout.
This will mark his first fight back after an eight month suspension and $2,400 fine.
Both of these fighters are red hot, but someone's zero has to go and it will take place LIVE on the Versus network at 9 p.m. ET this Sunday.
WEC 34: "Faber vs. Pulver" is headlined by the biggest featherweight title fight in recent memory. Urijah Faber will defend his 145-pound strap against MMA legend, Jens Pulver, in the evening's main event.
Just another reminder: It's FREE on Versus at 9 p.m. ET.
